traction control

wfmrules3 · 03-06-2012, 11:00 PM

Sometimes when I shift at low rpms the vhc kicks on and the car bogs really bad. Obviously this can be fixed by shifting at higher rpms but I was just wondering if this happens to other people and why.

Thanks.

how low rpms are you talking? I've never seen my vdc on unless I've done something purposely.

wfmrules3 · 03-06-2012, 11:14 PM

like 1500-2000 maybe a little lower. I didn't gun it or anything so I am confused when the vdc kicks on. It has happened a few times in 2nd and 3rd gear.

Skeeterbop · 03-06-2012, 11:17 PM

slick road conditions? I've never seen mine come on that low unless i either did something to cause it or it was cold on smooth pavement. I might also add that at that low of an rpm I have yet to have an issue with 3rd gear spinning except when I'm at the drag strip (but then my rpms aren't that low either).

wfmrules3 · 03-06-2012, 11:25 PM

dry conditions and I'm not gunning it at all. I don't think there is anyway the wheels are slipping. I've had the Z for about 3 weeks. It has happened 4 or 5 times. Weird I figured this would have happened to other people.

perhaps ur releasing the clutch too quickly so the clutch isn't grabbing, and thereby causing spin as if you kicked the clutch.

wdkwang · 03-07-2012, 02:33 AM

car feels like crap at 1500-2000rpm. live a little

If it is a smooth gear shift then it is not normal but if it is really jerky then it's normal.

Your not letting the clutch out properly.

give it more gas, you are bogging the engine by letting out the clutch pedal too early, or you are trying to use a gear that is too high. Like you are in 2nd or 3rd and you should be in 1st.

cheshirecat · 03-07-2012, 03:00 PM

imo, OP isn't shifting properly. No offense.

WhiskeyHotel · 03-07-2012, 04:12 PM

Agreed -sounds like bad technique....and trust me, I am an expert on bad technique - with nearly everything.

Based upon what you have said so far, one of the following is happening:

1. You need to learn how to drive stick.
2. You are on uneven ground/gravel/etc that is causing VDC to activate.
3. Your car is broken and needs to be fixed.

I highly doubt your problem is number 1 if you are not having these problems shifting at higher RPM's. Unless you mean you are shifting at 1500 RPM's, then yes, you are bogging the engine. Get your RPM's up. No idea why that would activate VDC though. Number 2 is easy enough to test and if the problem, easy to rememdy by chosing a different route. So my money is on numer 3, in which case, learn how to replicate the problem with consistency and take it to a dealer.

Unless the car is under the 1500 RPM mark or on decent incline, this engine will not bog down in any appreciable way. I routinely drive at sub-2000 RPM levels and while acceleration is indeed slower, bogging never occurs.

Also, I am using the term bogging to mean the engine is basically incapable of making the vehicle accelerate with the gas pedal on the floor.

Spikuh · 03-07-2012, 06:20 PM

So I'm out driving around going home from work (at a red light atm) trying to replicate your problem and for the life of me I am gettin nothing. Tried with synchro-rev on and then off using piss poor shifting and I get neither VDF kicking in nor the bogging problems. I am shifting sub-1500 and sitting on the 1k mark upon completing my shift.

I think it's your car...
